Paste or drop two XML documents in the shared Compare workspace. XML mode runs a line-level diff so tag, attribute, and text edits are easy to scan. Whitespace and attribute order on different lines can show as changes. Comparison stays on your device.

XML Compare is an XML-aware difference checker. Paste two documents and review added, removed, and changed lines in the shared Compare workspace.

Elements, attributes, and text nodes show up as the lines they occupy. A renamed tag or a changed attribute value is usually a changed line. Nested trees are not matched as independent XML nodes.

Insignificant whitespace is not ignored unless you turn on the workspace whitespace option. Indentation-only edits can still appear as diffs.

A plain text diff treats XML like any other string. XML mode starts with the XML document type selected and still uses the same side-by-side and unified views.

Comparison stays on your device. Nothing you paste is uploaded. Use URL Compare when you need to fetch HTML from live pages instead of pasting XML.

How to use this tool

1. XML Compare opens with document type set to XML. 2. Paste or drop the original markup on the left and the updated markup on the right. 3. Click Compare. 4. Review tag, attribute, and text line changes. 5. Optionally ignore whitespace if the documents were reformatted. Comparison runs in your browser.

Worked example

Example: compare <book id="1" lang="en"><title>Old</title></book> with a copy that changes the title and adds a second book. Compare highlights the title line and the extra element lines. Attribute order on the same line may stay unchanged; attributes split across lines can appear as edits.

When to use this

  • Reviewing XML config or feed updates before deploy.
  • Checking SOAP or XML API fixtures after a schema tweak.
  • Spotting a changed attribute value without reading the whole file.

Common examples

  • Config XML with a changed attribute on one element.
  • A feed item title update inside a larger document.
  • Pretty-printed XML vs the compact original.

Common mistakes

  • Assuming comments and declarations are skipped. This workspace diffs the text you paste, including comments if they are present.
  • Expecting attribute order to be ignored when attributes were rewritten onto new lines.
  • Comparing pretty-printed XML with minified XML and treating every wrap as a data change.

How it works

FAQ

Frequently asked questions

Does XML attribute order matter?

Attribute order on the same line may not change the diff. Attributes rewritten onto new lines, or whitespace-only reformatting, can still appear as line changes.

Are comments compared?

Yes, if they are in the text you paste. This workspace diffs the XML as text; comments are not stripped first.

Is my XML uploaded?

No. Comparison stays on your device.
